The best agreement was obtained with the inclusion of a fully screened core–hole and by using the finite difference method (FDM). Webb29 jan. 2024 · The core-loss spectrum is called the energy loss near edge structure (ELNES) spectrum, which is identical to the X-ray absorption near edge structure (XANES) spectrum observed using a synchrotron. ELNES and XANES commonly originate from an electron transition from a core orbital to unoccupied states [ 1, 2 ].
